Environmental Essay

Humans have been impacting the environment for a long time, but in Something New Under the Sun, J.R. McNeill argues that there are significant and qualitative differences in the effects our species is having on key earth systems in the last century or two. In a structured essay of 4 to 5 pages, identify three areas in which McNeill documents 20th century developments that represent historical shifts in the magnitude or effects that human actions are having on earth’s environment. Be specific and provide adequate explanation and examples to support your discussion of the three areas of change that you choose to focus on. (By “areas of change” I mean big topics such as energy, population, etc.)
